The albic horizon, a diagnostic subsurface horizon that is comprised of primary sand and silt particles that are light-colored because they lack clay or iron oxide coatings, is unique in that it is an eluvial horizon that is defined on the basis of a loss rather than a gain of weathering products. Over 3000 official soil descriptions were examined in the US Natural Resources Conservation Service databases...
The main objectives of the Global Soil Map (GSM) project are the development of high resolution maps for defined soil properties and new digital soil mapping tools. Although many current land use, land capability models and many soil related applications use soil type information, a new global soil type map is not among the objectives of the GSM project. In this presented research legacy data was...
As soils are facing considerable changes in climate, land use, land consumption, and degradation, it is vital to understand the characteristics of soils and their distribution, especially for soil management issues. In mountainous regions like the Alps, soils require specific attention as they provide a large variety of ecological functions, but also because of their vulnerability. However, pedological...
Machine-learning is the automated process of uncovering patterns in large datasets using computer-based statistical models, where a fitted model may then be used for prediction purposes on new data. Despite the growing number of machine-learning algorithms that have been developed, relatively few studies have provided a comparison of an array of different learners — typically, model comparison studies...
For more than sixty years the Antarctic Peninsula has experienced significant temperature increases that have accelerated glacial retreat. Glacial losses, along with the relatively warm and moist climatic conditions of the region, have increased the rate of soil development. The objective of this study is to study the properties and genesis of soils at Cierva Point, which is located in the zone of...
Amazonian Dark Earths (ADEs) are fertile soils for agricultural production as well as important archaeological resources for understanding the pre-Columbian past of the Neotropical lowland rainforest. ADEs are threatened by expanding land exploitation and there is a need to develop efficient approaches to soil mapping and analysis for documenting these soils. In this paper we assess the potential...
